Chapter 61 Artillery Section

【recently】

Zheng Kezang used the excuse of studying "Dongning Infantry Drill Code" to let Dongning Military Academy absorb many grassroots officers from Yuan Yongwei Town, Qiu Jiayi Army, and Zhu Tiangui Department.

None of the ministries had any objections, because Zheng Kezang said: New equipment can only be issued if new drills are learned.

Mastering logistics means mastering the lifeline, and these proud and powerful generals are now controlled by him.

The most important reason why Zheng Kezang is so active in letting them come to further their studies is the special buff of Dongning Military Academy. Officers from this military academy have a +20% loyalty to Zheng Kezang.

With this buff, the loyalty of officers who have taken courses here and graduated will be greatly improved.

The buff of Dongning Military Academy cannot be covered by all soldiers, but it is really practical.

When other places are conquered in the future, more military academies should be built to ensure sufficient martial virtue!

In addition to officers, Zheng Kezang also recruited outstanding artillerymen from various ministries and established an artillery department. After they completed their studies, they were sent back to various ministries to serve as artillery officers and teach.

Then we won’t talk about any principles, theorems or the like.

Zheng Kezang cleared his throat and suddenly said to Qin Zhiguo: "Zhiguo, summon all the students in the artillery department. These days, I will focus on teaching them. In short, they must learn a lot of knowledge about parabolas as soon as possible.

To improve the hit rate of cannonballs!”

Zheng Kezang believes that this is because the calculation method is the same and the process is the same. The only thing that changes is the number. You can remember it after calculating it several times.

Hearing a new term pop up from Zheng Kezang's mouth, Qin Zhiguo felt confused.

Soon, Qin Zhiguo, who had just mastered mathematics, fell into the vast sea of ​​parabola knowledge and could not extricate himself. The two calculated and operated the Hongyi cannon and found that the shooting was really accurate.

When Zheng Kezang found out about this, he called it "involvement". No wonder everyone had black eyes the next day. It was only the seventeenth century and they were already involved. Sure enough, silver was the only productive force.

Qin Zhiguo, commander of the Guards Artillery Battalion, was also at the scene to observe.

In order to get the money, many of these gunners stayed up all night last night, writing and calculating with oil lamps on.

Soon, he discovered a problem. Since the cannons of this era were all solid bullets, the emphasis was on impact, and they were mainly used to attack city walls, so there was not much requirement for aiming at the head.

This is actually a very simple parabola problem. If the warhead mass, initial velocity, and angle are known, a high school student can calculate the trajectory.

As a science student, Zheng Kezang still remembers this knowledge, so he can just prepare a textbook of his own.

Zheng Kezang originally thought that it would be good if seven or eight of the hundreds of gunners could learn it.

The veteran of the artillery department came up and explained: "Teacher, didn't the principal ask us in the artillery department to thoroughly study the parabola? We are all studying this!"

"Yes, principal!" Qin Zhiguo gave a standard salute.

After two days, Zheng Kezang saw that they had almost learned numbers, so he started teaching.

What Zheng Kezang is talking about is the formula, asking everyone to memorize it, and then put which number where. After the number is calculated, put it where. It just comes out after a mechanical application.

Moreover, craftsmen such as Su Laocheng have successfully developed the flowering artillery shell technology, which has the bonus of sweet gunpowder and is extremely lethal. This was fully demonstrated in the Battle of Zhugang.

Most of this operation relies on experience and feeling, and the error is very large. Whether you can hit it depends on luck.

There is no need for the soldiers who control the cannon to study in depth. As long as they learn trigonometric functions and parabolas, they may be able to greatly increase the cannon's hit rate!

"This is a gadget that can improve the hit rate of cannons! Remember the Arabic numerals you learned before, that is the basis." Zheng Kezang explained.

"Don't get excited, the top priority is how to teach these gunners how to calculate parabolas and functions." Zheng Kezang said calmly.

Speaking of which, blooming artillery shells were available in the late Ming Dynasty. When Zuo Zongtang was fighting the rebellion in the northwest, he excavated more than a hundred blooming shells from a Ming Dynasty fort site. He couldn't help but look up to the sky and sigh. There were such things in China three hundred years ago, but now they are

It was lost and even bullied by foreign powers.

On the other hand, the temptation of money was too great, which stimulated their potential. Zheng Kezang told them before the class started: the gunners who learned how to do it could receive two taels of silver.

But as soon as he drew this picture, he said what parabola, what initial velocity, what gravity acceleration...he did a lot of calculations, and it didn't take long for Qin Zhiguo to be confused!

"Principal, is this... possible?" Qin Zhiguo asked hesitantly: "Can we figure out where the cannonball landed?"

In this case, their experience is simply not suitable for generalization across the military.

It seems that Zheng Kezang must personally teach the gunners the great subject of mathematics.

The weather is better today, so Zheng Kezang came to the artillery section in person to see how they train.

As a result, on the next day, Zheng Kezang was surprised to find that half of them, who had no foundation in mathematics or physics, could actually calculate, and some of them could calculate quite quickly.

"Principal, I have an idea. Let the accountant in the logistics department teach them how to use Arabic numerals to lay the foundation, so that they can take your class." Qin Zhiguo suggested.

If we really wanted to talk about this, we would have to go back and teach junior high school physics and mathematics one by one.

So last night when military academy instructor Chen Wei was on inspection, he found the barracks of the artillery department brightly lit and felt strange. He hurriedly came over and asked, "Why are you so crazy? Are you writing, drawing, and reviewing here in the middle of the night? What else?"

"

Although these gunners are experienced, their artillery shooting relies entirely on experience. They judge the angle at which the shell should be fired, how far it can hit, how high it can shoot, etc. based entirely on experience.

There are only two big parts to talk about: one is parabola and the other is trigonometric functions.

In order to make it easier for his artillery officer Qin Zhiguo to understand, Zheng Kezang directly drew a picture to explain it to him.

"Principal, you are really a great talent. With this unique skill, the Tatars are in trouble!" Qin Zhiguo said excitedly.

"parabola?"

Chen Wei suddenly realized that he had also heard about this matter. Since it was the principal Zheng Kezang who was responsible for the matter, he did not want to interfere too much, so he said: "You guys should go to bed early and don't affect the rest of the students in the infantry and cavalry departments."

"It's almost ten!" Zheng Kezang replied.

"Good idea, Zhiguo, I'll leave this matter to you." Zheng Kezang patted him on the shoulder.

Therefore, in the future war mode, artillery must be accurate, and the artillery shells must be aimed at the opponent's infantry.

What you learn on paper is ultimately shallow, but you must know that this matter must be practiced. Learning parabolas and trigonometric functions is just the beginning for the gunners. How to apply them in actual combat is the key.

They still have a long way to go.

"Zhiguo, your mission is very heavy, do you understand?" Zheng Kezang said to Qin Zhiguo next to him as he watched the artillerymen's intense training.

"Understood, I promise to complete the principal's tasks!"
